ASW 28 problem with left aileron

Good evening, I am configuring an ASW 28 motor glider.
FC Matek H743 Wing V3 with Ardupilot 4.5.2.
Right aileron on S3, left aileron on S4. Configured: SERVO3_FUNCTION=4 and SERVO4_FUNCTION=4. The right aileron moves correctly, the left one shows no signs of life. At the link the configuration file. 2024-10-16-config.param - Google Drive
Where am I going wrong?
Thanks

The configuration looks right. I think it’s time to get out the multi meter and the servo tester and rule out that side.

Quick test:
First check solderng if looks fine
Swap the Servo cables on your FC.
If the failure is the same β†’ problem with left servo / servo cable
If the failure changed to right aileron β†’ problem on FC side

I checked the servo and the connection cables. They are ok. Now I have to check the soldering and change pad to see if it is a problem of the FC. Thanks also to Juergen Fahlbusch for the advice.

Good evening, it was a cable wiring problem. Solved.
I kindly ask if you can tell me how to set the falesave in case of loss or deterioration of the radio link.
I also ask how to set the battery type, I would like to equip it with Li-ion, the voltage and the current.
Thanks
Walter
